The Stock and Options Trading Data Provider API is a REST API that provides stock and options data, including company information, market-related data, and option details. It can be used by developers to build mobile/web applications for retail investors/stockbrokers, financial analysts, and individuals looking to learn about online trading. The API offers two endpoints: Options and Straddle, both of which accept a ticker parameter and return relevant data. RapidAPI provides code snippets in various programming languages, including Java, Python, PHP, Ruby, and JavaScript, making it easy for developers to integrate the API into their applications. The API is economical, with a free plan allowing 5 requests per day, and offers options data not found in other finance APIs.
